JOHN HILDEBRAND, on TANEYTOWN, MARYLAND, AsSIeNoR To HIMSELF AND JACOB 'FRINGERQ OF SAME PLACE.

Lette/rs Patent No. 103,744, dated .May 3l, 18,70.

Be itknown that I, JOHN HILDEBRANn, of 'laneytown, in the county of Carroll and State of Maryland, have invented a new and useful Improvement in Fruit-Driers; and I do herebydeclare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing-forming a pal-trot' this specification, in which- Figure 1 is a sectional eievation;

Figure 2, a horizontal section;

Figure 3, an elevation of one of the rakes Figure 4, an elevation of one of the plates 7;; and

Figure 5 is a sectional elevation of the shield h` rlhis invention consists mainly in the combination of pans for holding fruit, whose bottoms are perfoi rated, with drums which communicate with the pipe by which the productsoi' combustion are conveyed away froma furnace, when the drums areI so located as to radiate heat into the pans, for the purpose of drying the fruit, the pans, drums, and furnace being inclosed within a suitable case.

In the drawing- A is the case. i

a are semi-tubular doors, hinged tothe sides of the case.

b are openings made horizontally in the sides of the case.

c are circular pans, whose bottoms are provided with perforatious d, the pans being placed in the openings b, so as to be half inside the case, and half within the semi-tubular doors, when the latter are closed and pivoted attheir centers so as to be easily rotatedby hand,

the pans, in this instance, being arranged in four vertical series, one at each side of the'case.

mis the furnace, located at the bottom of the case. e is the smoke-pipe. f are drums, arranged in. a vertical series on the smoke-pipe, communicating therewith, and extending between the paus, as shown in fig. 1, so as to radiate r, heated air upward through the perforations in the bot-` tom of the paus, and downward directly into thepaus, by which process the fruit is dried.

Sufficient ventilation is secured by throwing open l the doors a, and thns exposing the outer halves of the pans.

semicircular shield, h, of sufficient dimensions to cover the exposed parts of the pans, is placed over the upper pan of each series, and held there,'for the purpose of shedding rain, by a ange on the straight side of the shield, projecting into a recess in a horizontal bar, t', secured to the outside of the case, above the door, for this purpose. v

When the open doors -aiord too much ventilation, plates lc, tig. 4, are placed diametrically in the paus c, and attached to the sides of the case, so as to close the openings b, except as to those portions of said openings which are outside of the pans. l

It is necessary to turn the pans, from time to time, on their pivots, in order to subject all the fruit equally to the action of the heated air.

When the piates It' are in place, they keep all the fruit withinthe case, and, as the pans are'turned,

cause'au agitation ofthe fruit, which exposes all parts ot" each piece in turn to the lieated air.

When theplates It are disused, Takes l, fig. 3,'are substituted fcr them.

The rakes allow the fruit to come forth from the case as the pans turn, and agitate it as the pieces-pass beneath them.

Havingth ns described my invention,

. That I claim as new, and desire tosecnre by Lettersl Patent, is

l'. The combination ofthe.perforated'pansc, whether arranged in vverticalseries or not, with the drums f,

in the manner and for the purpose described.

2. The combination of the pans c with the rakes I,

as and for the object specific 3. The combination of the pans c with the plates It, as and to the end set forth'.

4. vThe combination of the pans c withl the shield 117, as and for the object explained.

To theabove specification of my invention, I have signed my hand this 26th day of April, 1870.

' JOHN HlLDEBR'AND.
